NTRODUCTION
Custom categorization uses SurfControl’s Virtual Control Agent™ (VCA) technology. The VCA evaluates
unknown Web destinations, reading and analyzing content page by page. It then uses cutting-edge
artificial intelligence algorithms to study and classify each Web page into one of the SurfControl Web Filter
categories. This allows sites initially shown as ‘Uncategorized’ in the Monitor to be categorized more
meaningfully.
